As many RPI2 styled interfaces provides 1 or 2 UARTs.

Non necessarily ... There is a second UART, the UART4 available on pins 19/21, but it is shared with SPI pins.
It is better to use those SPI pins for attaching the SC16IS752 chips ...
Hi, I just obtained my first Rock64, may i know how to enable SPI pin with SC16IS752 step by step in Linux?
TQ

You will need to compile your own kernel since most of them don't provide SC16IS752.
You will also need to add device tree SC16IS752 node inside SPI node.

Concerning a second NIC, I use a USB 3 Gigabit Ethernet adapter, it works quite well. To configure it, one needs to add a yaml file in /etc/netplan (in ubuntu)

Hi LMM, sorry to resume an old post Smile What adapter do you use? I want to buy one for my Rock64 but I don't know if every USB3 to Ethernet adapter is the same or only some work with Rock64 (with Armbian in my case). Many thanks!

Hi, I suppose that all are compatible. I use this one (french amazon - german store) :
